VELOCIPEDE.

FJFECIPICA'I'IQN forming part of Letters Patent No. 327,952, dated October 6, 1885.

Application filed July 18, 1885.

To all whom it may concern.-

Be it known that I, FREDERICK JUNGE, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Velocipedes; and I hereby declare the following to be a full, clear, and exact description of the same.

It is my object to provide mechanism by means of which such vehicles may bepropelled with great ease by a construction which permits the operator to bring into play the full force of the muscles of the back and thighs as well as those of. the feet and lower limbs, which latter alone in the constructions of propelling mechanism heretofore generally em-' ployed in such devices have been capable of full utilization in actuating the machine.

It is also my object to overcome the objectionable feature of great weight and cumbersomeness heretofore entailed by the use of foot-levers in such vehicles,by providing them of a peculiar construction, whereby great strength is secured by the expenditure of a minimum amount of material, thereby insuring the desired lightness. Another objection heretofore incident to the use of foot-levers,and which I overcome, results from their liability to become temporarily valueless for commucating motion to the axle whenever the latter, as sometimes happens, stops with its cranks on a dead-center.

To these ends my invention consists in a velocipede actuated through the medium of levers of peculiar construction, connected by suitable mechanism with the driving-wheels of the vehicle, pivoted in such a position that a motion of the legs of the operator forward and backward, instead of upward and downward, whereby, when seated in an adjustable chair provided for that purpose, the operator is afforded a brace, thus permitting the use of the muscles of the back and thighs as well as those of the feet and lower limbs. My invention also consists in starting mechanism whereby, when the Vehicle has come to rest on a dead-center, it may be started sufficiently to bring the crank-motion again into play; and my invention still further consists in the general construction of my improved device and in various details of construction and com- Serial No. 171,929. (No model.)

binations of parts forming the same, all as hereinafter more particularly set forth.

Referring to the drawings, Fig. l is a plan view of my improved velocipede; Fig. 2, a sectional view in elevation taken on the line 2 2 of Fig. 1, and viewed in the direction of the arrows; Fig. 3, a front elevation of the forward movable guide-wheels forming part of the steering-gear; Fig. 4, a sectional view in elevation taken on the line 2 2 of Fig. 1, and viewed in a direction contrary to the arrows, showing the mechanism employed as a starting device, and Figs. 5 and 6 detail views.

A represents the body or frame-work of the Vehicle, carrying a floor, A, and formed, preferably, of wood. The body A is supported upon driving-wheels B, actuated by the propelling mechanism hereinafter de-- scribed, and upon steering-wheels G, at the front of the device, and forming a portion of the steeringgear, also hereinafter described.

Toward the rear extremity of the body A is secured a transverse bolster, t, forming a support for the propelling mechanism referred to. Foot-levers D, comprising light angular frames of the shape illustrated, and strengthened by means of braces on, and forming levers of the second class, are pivoted at one extremity to the bolster t, as shown at s, and are provided toward their opposite extremities with pivotally-attached shoes affording footrests r. Pitmen q afford the necessary connection of the foot-levers with the drivingwheels through cranks p, formed on an axle, p, to which latter the driving-wheels are rigidly secured. The axle 1), supported in bearings 19 upon the frame A, is divided, as shown in Fig. 6, readily to permit turning, and, when the velocipede is running on a curve, to allow the outside driving-wheel to revolve faster than its mate, thus preventing the loss of power and increased labor of propulsion nec essarily incident to the employment of a single undivided shaft, which, of course, entails the slipping of one wheel, as both must revolveat the same speed. I prefer that the length of the pitmen q shall be so regulated with relation to the pivotal adjustment of the leversD upon the bolster t that the revolution of the cranks 10 shall be within the truss-work of the lever, as shown in the drawings, though this arrang ment is not essentiallya feature of my invention, and many of the advantages attained by the use of my peculiar form and position of foot-lever may be secured if the pitmen are sufficiently prolonged to bring the levers entirely below the cranks. In this case the pivotal bearings 8 would also have to be formed sufficiently low down to afford to the foot-levers the same relative position as that shown in the drawings, as this position,in which the foot-levers are sufficiently inclined to allow a motion in operating the propelling mechanism somewhat forward and backward of the legs of the operator, instead of upward and downward merely, is regarded as of great importance.

WVhenever by chance the vehicle stops with its propelling mechanism on a dead-center, which may occur when the device is arranged to be propelled by a single operator, and pro vided for the purpose with only two cranks on the axle and one pair of levers D, I employ as a starting device the contrivance illustrated in Fig. f the drawings. One portion of the divided axlep is provided with a secondary crank, 19*, (see Fig. 6,) at a right angle to a crank, p, so that it can never be on a dead-center with it. A lever, 0,-pivoted at one extremity to a support, 0, and provided at its opposite extremity with a handle, 0', is fulcrumed to a connecting-rod, a, which in turn may be readily hooked upon the crank 12 by means of a hook, n, whenever the use of this device becomes necessary. After being so connected, movement of the handle 0 will start the velocipede sufficiently to bring the eranksp off the dead-center and the propelling mechanism again into action, when the connecting-rod a may be unhooked and its eX-' tremity n placed in a chock, Z, provided for the purpose of holding it when not in use. When thus disconnected, the starting mechanism occupies the position shown by the dotted lines in Fig. 4:.

E is an adjustable chair for the operator, having a back, E, securely braced and sup ported upon bearings moving in dovetailed slots 70, (see Fig. 5,) and adjustable therein by means of set-screws 7c.

The steering-gear, hercinbefore referred to, whichl prefer to employ, is controlled by across-head, F, upon a shaft, F, formingahan- (lle within convenient reach of the operator. Motion of the handle F is communicated to the steering-wheels C by means of ropes or chains 2', secured at each end to a cross-head, h, formed upon the rotatory support h, provided for the steering-wheels, and leading backward around a drum or pulley, g, rigidly secured upon the'shaft F toward its lower eX- tremity. Any other suitable form of steeringgear may be used with my devicesuch, for instance, as a single wheel, instead of the two which I prefer to employ; or a lever leading backward to within reach of the operator from the wheel or wheels may control it or them, if desired.

Although the drawings illustrate only one set of foot-levers and make provision for one operator only, it is evident that two or even more persons might unite in operating my improved velocipede by suitably increasing the number of foot-levers and providing either separate seats or enlarging the capacity of the one.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a velocipede, of a chair, E, supported upon'the platform of the vehicle, a divided driving-shaft, 19, pro

vided with cranks p, foot-levers D, comprising each a frame strengthened with suitable braces and pivotally connected with the vehicle to cause the foot-rest portions thereof to extend above the platform of the vehicle to a position accessible to the feet of the operator,

whereby the levers may be actuated by forward and backward movement of the legs,and the back of the operator braced against the back of the chair-pitman q, connecting the levers with cranks upon the shaft, and starting mechanism, substantially as described, detachably adjustable upon a crank of the shaft, the whole being constructed and arranged to operate in the manner set forth.

2. The combination,with a velocipede, of a chair adjustably supported upon the platform of the vehicle, to be moved forward and backward thereon, a divided driving-shaft, 10, provided with cranksp, foot-levers D, comprising each a frame strengthened with suitable braces and pivotally connected with the vehicle to cause the footrest portions thereof, having shoes 1*, pivotally secured upon them, to extend above the platform of the vehicle to a position accessible to the feet of the operator, whereby the levers may be actuated by forward and backward movement of the legs, and the back of the operator braced against the back of the chair-pitman q, connecting the levers with cranks upon the shaft, starting mechanism, substantially as described, detachably adjustable upon a crank of the shaft, and steering mechanism, substantially as described, operated from a position in proximity to the chair, the whole being constructed and arranged to operate in the manner set forth.
